A movement quantity calculation unit 102 calculates an image movement quantity between a new frame and a previous frame, each including image data in frame units comprising a dynamic image photographed one after another by a camera 1, based on difference in image data between the frames. A storage control unit 104 stores in a time-lapse photographed image storage area 107 either the image data of the new frame or that of the previous frame as a time-lapse photographed image in the case where the image movement quantity calculated by the movement quantity calculation unit 102 has changed from being equal to or greater than a predetermined value to being less than the predetermined value.
